If you need information, chances are Siri can help you find it. Apple currently enables Siri to search Yelp for restaurant info, Google (or Yahoo! or Bing) for general information, and Wolfram|Alpha for computational knowledge. You can use Siri to find anything you would normally type into a web search box, only there's no typing needed. Just ask, and you'll get back everything from the latest celebrity gossip to the answers to that nagging math questions to a listing of the best free apps for your iPhone.

If you have the need to check stocks or find out what the different exchanges are trading at Siri can help you do so and give you lots of up to the minute information about all your investments. Whether you want to find out if APPL is up, or the DOW is down, and by how much, Siri has you covered. (In terms of information, not money!)
